These solutions greatly simplify the content creation process compared to traditional methods, but it is difficult to modify the content of the scene. We propose a novel approach to create scenes by composing (parts of) multiple captured scenes. The main difficulty of such compositions is that lighting conditions in each captured scene are different; to obtain a realistic composition we need to make lighting coherent. We propose a two-pass solution, by adapting a multi-view relighting network. We first match the lighting conditions of each scene separately and then synthesize shadows between scenes in a subsequent pass. We also improve the realism of the composition by estimating the change in ambient occlusion in contact areas between parts and compensate for the color balance of the different cameras used for capture. We illustrate our method with results on multiple compositions of outdoor scenes and show its application to multi-view image composition, IBR and textured mesh creation.","PeriodicalId":91160,"journal":{"name":"Proceedings.

The weak association model (WAM) suggests that distraction caused by disjointed features may be associated with the weak association. People characterized by field independent (FI) or field dependent (FD) cognitive style have different abilities in handling sustained attention, thus they may perform differently in the flow-performance link. To explore the role of the field dependence-independence (FDI) construct on the flow-performance link in virtual reality (VR), we developed a VR experimental environment, based on which two empirical studies were performed. Study 1 revealed FD individuals have higher dispersion degree of fixations and showed a weaker flow-performance link. Next, we provide visual cues that utilize distractors to achieve more task-oriented attention. Study 2 found it helps strengthen the task performance, as well as the flow-performance link of FD individuals without increasing distraction. This paper helps draw conclusions on the effects of human diversity on the flow-performance link in VEs and found ways to design a VR system according to individual characteristics.","PeriodicalId":91160,"journal":{"name":"Proceedings.

Unlike the previous works using 3D finite elements, we use a 2D shell element to avoid inefficient or undesired tessellation due to the thin structure of facial muscles. To simplify the analysis and achieve real-time performance, we adopt real-time thin shell simulation of [Choi et al. 2007]. Our facial system is composed of four layers of skin, subcutaneous layer, muscles, and skull, based on human facial anatomy. Skin and muscles are composed of shell elements, subcutaneous fatty tissue is assumed as a uniform elastic body, and the fixed part of facial muscles is handled by static position constraint. We control muscles to have stretch deformation using modal analysis and apply mass-spring force to skin mesh which is triggered by the muscle deformation. In our system, only the region of interest for skin can be affected by the muscle. To handle the coupled result of facial animation, we decouple the system according to the type of external forces applied to the skin. We show a series of real-time facial animation caused by selected major muscles that are relevant to expressive skin deformation. Our system has generality for importing new types of muscles and skin mesh when their shape or positions are changed.","PeriodicalId":91160,"journal":{"name":"Proceedings.
